Ans: The magnetic field is maximum at the centre, and it goes on decreasing as we move away from the centre of the circular loop on the axis of the loop.Dec 16, 2021
What is the magnetic field on the axis of a circular current loop?
What is the magnetic field at the centre of a circular loop carrying current?
The magnetic field at the centre of a circular loop carrying current is zero.
What is the magnetic field on the axis of the ring?
Field of a Single Ring Figure %: The field created by a ring. If the ring lies in the x-y plane, then the field lines point in the positive z direction It is clear that on the axis of the ring, the field lines point straight up, perpendicular to the plane of the ring.
What is the magnetic field at a point on the axis of the current element?
(i) The magnetic field of a current element is minimum (which is zero) along the axis of a current element.
What is the magnetic field at the Centre of the circular loop shown in Figure?
The magnetic field at the center of the loop is BL. Now, a circular loop of radius R/n is made from the same wire without changing its length, by unfolding and refolding the loop, and the same current is passed through it.
What is the magnetic field at the Centre C?
According to diagram in the question, magnetic field at the centre C will be sum of the magnetic field due to straight part B1 and magnetic field due to rircular part R2 ∵ From Maxwell's right hand thumb rule direction of both magnetic field at the point C will be same and above the plane of paper.
What is magnetic field formula?
The magnitude of the force on a wire carrying current I with length L in a magnetic field is given by the equation. … F=ILBsinθ where θ is the angle between the wire and the magnetic field. The force is perpendicular to the field and the current.
What is the expression for magnetic field?
It is written in integral form as ∮B⋅dl=μ0Ienc ∮ B ⋅ d l = μ 0 I enc , where Ienc is the enclosed current and μ0 is a constant. … It is found to be F=Bilsinθ F = Bi l sin θ , where ℓ is the length of the wire, i is the current, and θ is the angle between the current direction and the magnetic field.
What is the magnetic field on the axis of a current carrying conductor?
A current carrying wire generates a magnetic field. According to Biot-Savart's law, the magnetic field at a point due to an element of a conductor carrying current is, Directly proportional to the strength of the current, i. Directly proportional to the length of the element, dl.
